Connecting users through WebDirect

I'm in the process of building a WebDirect user portal that will help outside vendors connect to our database and input time billing and expenses data. We decided to NOT give vendors access to our entire database and build a separate "Front End" portal. Now that we have the "Front End" portal established, I'm having issues connecting the two FileMaker Solutions together.

1. I CAN access the "front end" portal layouts and log in with my "back end" user credentials.

2. There's no data showing once I am in the portal. Which means no project lists for me to access and input my time billing and expenses pertaining to a project.

THis is possibly a privileges issue. Are there Privilege Sets for the web users in your main solution that explicitly give access via WebDirect™ connections? Also the "front-end" must have Table Aliases for the tables in the main file you want them to access.

If you do have this set up, then something else is afoot. Perhaps one of the web experts can assist.
